Improvement in shoulder-tools for shoemakers



UNITED STATES PATENT QFFICE.

CHARLES MALHOIT, OF SUTTON, MASSACHUSETTS.

IMPROVEMENT IN SHOULDER-TOOLS FOR SHOEMAKERS.

Specification forming part of Letters Patent No. 118,620, dated August 29, 1871.

To all whom it may concern:

Be it known that I, CHARLES MALHoIr, of Sutton, in the county of Worcester and Comm onwealth of Massachusetts, have invented certain new and useful Improvements in Combined Stone and Iron Shoulder-Tool for finishing the edges of boots and shoes; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompany ing drawing which forms a part of this specification, and in which- Figure 1 represents a perspective view of my combined stone and iron shoulder-tool. Fig. 2 represents a central longitudinal section of the same. Fig. 3 represents a transverse section at line A B, Fig. 1.

To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail.

The nature of my invention consists in a shoulder-tool, constructed substantially as hereinafter described.

In finishing the edges of boots and shoes it is desirable to have some rough shoulder-tool, to shoulder in the paste or other dressing used upon the edges in the preparatory process, and afterward to use some smooth shoulder-tool for polishing the edges as a finishing process.

For the first part of the process, stones having a sandy grit have been found preferable to other material, and for the latter part of the process iron shoulders are generally used. The ordinary method requires the use of two separate and dis tinct tools, and as the tools have heretofore been constructed it has been found difficult to make up the edges with the stone in such a manner that the iron shoulder would fit accurately thereon, and when this is not the case the iron or polishing-shoulder necessarily changes the conformation of the edge after the dressing has been shouldered in, and thus breaks up the fiber of the leather and interferes with the perfect polishing of the edge. This difiiculty is wholly obviated by the use of my combined stone and iron shoulder-tool, which consists of a short body or bar of iron (marked A in the drawing) cornered and rounded so as to fit the hand, and upon the ends of which are arranged the shoulders B, O, D, and E, those on the same end being separated from each other by the tongues F, which are wholly of iron. The shoulders and E are formed directly upon the iron, while the shoulders B and D are made of pieces of stone cut to the proper form and secured to the iron body A by means of some suitable cement. The stone pieces are provided with tongues a, which fit into mortises or slots formed in the ends of the iron body A, in the manner shown, whereby a secure and permanent attachment is produced. The stone edge forming shoulders B and D are fitted to exactly correspond in shape with the iron polishing-shoulders at the opposite end of the body A, so that when using the tool it is only necessary to reverse the position of the tool within the hand, when changing from the stone to the iron or polishing-shoulder, whereas with the ordinary method the tool requires to be laid down and a separate tool taken up; and when taking'into consideration the fact that the operator is required to perform this slight operation hundreds of times while doing an ordinary days work it will readily be seen that by the use of my improvement a considerable amount of time and labor is saved, and a great deal of inconvenience obviated.

By this manner of construction I am also enabled to obtain a stone shoulder having the required degree of roughness, while the tongue F which runs against the bottom of the sole, being of iron, does not abrade or roughen the corner of the sole, and thereby interfere with the free and perfect action of the tool.

The tool can be made with a greater number of shoulders when desired, and the shoulders may be made of any size to suit the thickness of the soles upon the boots and shoes whereon the tool is used.

Having thus described my improved combined stone and iron shoulder-tool for finishingboots and shoes, what I claim therein as new and of my invention, and desire to secure by Letters Patent, 1s-

A shoulder-tool for use upon boots and shoes, constructed with an iron handle part, A, metallic tongues and shoulders F, O, and E, and stone shoulders B D, substantially in the manner shown and described.
